.gles to the shaft axis, and thereby cause the cam surfaces of the rollers to press againstthe plate 31, which is held against longi- .tudinal movement by the sleeve "18.. Conseuently, when the speed is such that the action of the roll rs can overcome the pressure of spring the governor moves the shaft with its commutator, armature, and friction wheel rearwardly, longitudinally of the casing, so that when the speed of the fly.

wheel, or prime mover tends to transmit ex 15" cessive speed to the dynamo, the governor acts to withdraw the friction wheel from the prime mover, and thereby to maintain a substantially constant predetermined speed of the dynamo, which may be varied by the adjustment of the spring. tension.

While I have herein described in detail a specific embodiment of my invention, it will be apparent that many changes in the shape and construction of the parts may be made without departure from the spirit of the invention, within the scope of the appended claims.

What I claim is: p 1. The combination of a shaft mounted for sliding and rotary movement; an abutment fixed longitudinally with respect to the-shaft, and a governor'carried by the shaft, comprising bearing plates, one on each side of the shaft, ecccntrica-lly mounted rollers therebetween, movable under the influence of centrifugal force to act u on the abutment to move the shaft axia ly,- and yielding means acting upon the end of the shaft opposing such movement of the shaft. 2. The combination of a shaft mounted for rotation and axial movement; yielding means acting upon the end of the shaft opposing axial movement thereof in one direction; an abutment fixed longitudinally with respect to the shaft, and a governor on such shaft, comprising a bearing plate positioned longitudinally by the abutment; a frame, rotatable "with the shaft and carrying the plate therewith; and eccentrically mounted rollers within the frame, arranged when thrown outward by centrifugal action to exert a pressure'upon the plate, tending to force the shaft axially against the tension of its spring.

3. The combination with a shaft and bearings therefor, wherein the shaft,is axially movable and rotatable; a' core, connected with theshaft; side plates connected with the core; a bearing platev positioned laterally by the side plates, but movable'ax'ially with respect to the shaft, and positioned longi-j tudinally by the shaft bearing, rollers eccentrically mounted in the si e' plates, arf ranged for cooperation with the bearing plate to tend to move the-shaft. aiiially un der the infiuenceof centrifugalaction; and

ment of the shaft.

a spring arranged to resist sucha-xial move;

l. In a device'of th'echa-iacter described,

an engine fly wheel, a'friction pulley for coaction therewith, a longitudinally, slid; able shaft and. means for a so sliding the.

shaft to vary the position of the pulley with respect to the ,fly wheel, 'comprisi tionary abutment, two plates rotate leg with the shaft on opposite sides thereof, weights journaled in said platesadaptedto bemoved} by centrifugal force to impinge againstthe stationary abutment and thereby move the shaft. 1'

5. The combination with a :friction d'riving pulley, of a speed overnor comprising a longitudinally movab e shaft, acoact-ing friction pulley afiixedjtheret-o adapted and arranged to engage said driving pulley,

means for yieldingly eifecting such engagement, 1' centrifugally operated device for separating said ulleys comprising a core secured to said s aft, a late on each side thereof afl'ording bearings for movable weights, weights journa-l ed .in said plates adapted to be moved by centrifugal effect,

and a relativelystationary abutment against which said weights impinge to move the driven pulley out of engagement with the
